Trends of recanalization therapies and state of art for ischemic stroke treatment in Campania region, Italy.

BACKGROUND: According to the last Italian report by the Ministry of Health in 2018, the estimated number of acute ischemic strokes (AIS) in Campania is 10,000/year, with an expected number of 1390 intravenous thrombolysis (IVT) and 694 mechanical thrombectomies (MT). In 2017, only 1.5% of expected patients received IVT and 0.2% MT. This study analyzed the trend of IVT and MT in 2019-2020 and depicted the state of art of Stroke Care in Campania. METHODS: From the regional health task force, we obtained the hospital discharge forms from all private and public hospitals in Campania; we selected patients with a principal diagnosis of AIS and measured the rate of patients admitted to neurology units and the rate of IVT, MT, and IVT + MT for both 2019 and 2020. RESULTS: In 2019, we observed 4817 admissions for AIS; 2858/4817 (59.3%) patients were admitted to neurology units. Out of 4817 patients, 192 received IVT, 165 MT, and 131 IVT + MT (488 treated patients; 10.1%). In 2020, we observed 4129 admissions for AIS; 2502/4129 (62.7%) patients were admitted to neurology units. Out of 4129 patients, 198 received IVT, 250 MT, and 180 IVT + MT (628 treated patients; 15.2%). These results showed that despite a reduction of AIS admissions in 2020, the relative and absolute rate of recanalization treatments increased. However, the number of patients who were not admitted to neurology units nor received acute treatments remained dramatically high. CONCLUSION: Despite the development of acute treatments, the Campania Stroke Network still needs significative efforts to improve.

A case of febrile infection-related epilepsy syndrome (FIRES) in young adult: still a diagnostic and therapeutic challenge.

A new onset of status epilepticus in a previously healthy adult preceded by a recent minor febrile infection represents a diagnostic and therapeutic challenge in clinical practice. Considering the broad spectrum of epileptic encephalopathies caused by autoimmune mechanisms, differential diagnosis for new-onset refractory status epilepticus (NORSE) should include febrile infection-related epilepsy syndrome (FIRES), in order to not underestimate the underlying etiological condition triggering epilepsy in non-epileptic patients (Hon et al. in Recent Pat Inflamm Allergy Drug Discov 12:128-135, 2018). We report a case of acute encephalopathy with refractory seizures after a febrile illness (FIRES) in a young adult with complete remission of symptoms as well as dramatic improvement of EEG abnormalities following intravenous immunoglobulin and proper antiepileptic medications. We conducted an extensive workup including lumbar puncture, blood tests, EEG serial monitoring, MRI brain, total body CT scan, and PET brain with FDG to shed light on the etiology of the disease.

Migraine in menopausal women: a systematic review.

Evidence suggests that migraine activity is influenced by hormonal factors, and particularly by estrogen levels, but relatively few studies have investigated the prevalence and characteristics of migraine according to the menopausal status. Overall, population-based studies have shown an improvement of migraine after menopause, with a possible increase in perimenopause. On the contrary, the studies performed on patients referring to headache centers have shown no improvement or even worsening of migraine. Menopause etiology may play a role in migraine evolution during the menopausal period, with migraine improvement more likely occurring after spontaneous rather than after surgical menopause. Postmenopausal hormone replacement therapy has been found to be associated with migraine worsening in observational population-based studies. The effects of several therapeutic regimens on migraine has also been investigated, leading to nonconclusive results. To date, no specific preventive measures are recommended for menopausal women with migraine. There is a need for further research in order to clarify the relationship between migraine and hormonal changes in women, and to quantify the real burden of migraine after the menopause. Hormonal manipulation for the treatment of refractory postmenopausal migraine is still a matter of debate.

Migraine and body mass index categories: a systematic review and meta-analysis of observational studies.

BACKGROUND: Several studies have assessed the associations between migraine and underweight, pre-obesity or obesity, with conflicting results. To assess the consistency of the data on the topic, we performed a systematic review and meta-analysis of the available observational studies. METHODS: Multiple electronic databases were systematically searched up to October 2014 for studies assessing the association between migraine and body mass index categories (underweight, pre-obesity, or obesity). RESULTS: Out of 2,022 records, we included 15 studies. When considering the 11 studies following the World Health Organization BMI cutoffs, we found an increased risk of having migraine in underweight subjects (pooled adjusted effect estimate [PAEE] 1.21; 95% CI, 1.07-1.37; P = 0.002) and in obese women (PAEE 1.44; 95% CI, 1.05-1.97; P = 0.023) as compared with normal weight subjects; additionally, pre-obese subjects had an increased risk of having chronic migraine (PAEE 1.39; 95% CI, 1.13-1.71; P = 0.002). When considering all the 15 studies, we additionally found an increased risk of having migraine in obese as compared with normal weight subjects (PAEE 1.14; 95% CI, 1.02-1.27; P = 0.017); additionally, obese subjects had an increased risk of having chronic migraine (PAEE 1.75; 95% CI, 1.33-2.29; P < 0.001). The pooled analysis did not indicate an increased risk of having migraine in pre-obese subjects. CONCLUSIONS: The meta-analysis of the available observational studies suggested an association between migraine and obesity likely mediated by gender and migraine frequency. Further studies taking into account gender, migraine type, frequency, activity, and duration could provide more robust evidence.

The renin-angiotensin system: a possible contributor to migraine pathogenesis and prophylaxis.

The presence of a tissue-based renin-angiotensin system, independent of the systemic one, has been identified in several organs including the brain. Experimental models have suggested the involvement of the renin-angiotensin system in neurogenic inflammation, susceptibility to oxidative stress, endothelial dysfunction, and neuromodulation of nociceptive transmission, thus potentially contributing to the pathogenesis of migraine. Genetic factors that increase susceptibility to migraine may include angiotensin-converting enzyme polymorphism, although available data are controversial. Clinical studies have suggested that angiotensin-converting enzyme inhibitors and angiotensin receptor blockers may be effective in migraine prophylaxis. However, further research should clarify whether the postulated preventive effect is attributable to a pharmacological action over and above the antihypertensive effect and should test their tolerability in subjects with normal blood pressure values. In patients with contraindications or not responding to conventional prophylactic drugs and in patients with comorbid arterial hypertension, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers may be used for migraine prophylaxis.

Migraine and hemorrhagic stroke: a meta-analysis.

BACKGROUND AND PURPOSE: Several studies have assessed the possible increased risk of hemorrhagic stroke in migraineurs, drawing differing conclusions. No meta-analysis on the topic has been published to date. METHODS: Multiple electronic databases (MEDLINE, EMBASE, Science Citation Index, and the Cochrane Library) were systematically searched up to March 2013 for studies dealing with migraine and hemorrhagic stroke. We selected case-control and cohort studies with a clear definition of the diagnostic criteria for migraine and hemorrhagic stroke, using an adjusted model or a matching procedure that could control for potential confounders, and reporting effect estimates with 95% confidence intervals (CIs) or enough data to allow calculation of those numbers. Adjusted odds ratios and hazard ratios were used to estimate effect size. RESULTS: Of 11 264 records, we identified 8 studies (4 case-control and 4 cohort studies) involving a total of 1600 hemorrhagic strokes, which were included in the meta-analysis. The overall pooled adjusted effect estimate of hemorrhagic stroke in subjects with any migraine versus control subjects was 1.48 (95% CI, 1.16-1.88; P=0.002), with moderate statistical heterogeneity (I(2)=54.7%; P value for Q test=0.031). The risk of hemorrhagic stroke in subjects with migraine with aura (1.62; 95% CI, 0.87-3.03; P=0.129) was not significant. Compared with control subjects, the risk of hemorrhagic stroke was greater in females with any migraine (1.55; 95% CI, 1.16-2.07; P=0.003) and in female migraineurs aged less than 45 years (1.57; 95% CI, 1.10-2.24; P=0.012). CONCLUSIONS: Available studies suggest that subjects with migraine have an increased risk of hemorrhagic stroke. Further studies are needed to address the hemorrhagic stroke risk according to migraine type, age, sex, and hemorrhagic stroke type.

Peripheral vascular dysfunction in migraine: a review.

Numerous studies have indicated an increased risk of vascular disease among migraineurs. Alterations in endothelial and arterial function, which predispose to atherosclerosis and cardiovascular diseases, have been suggested as an important link between migraine and vascular disease. However, the available evidence is inconsistent. We aimed to review and summarize the published evidence about the peripheral vascular dysfunction of migraineurs.We systematically searched in BIOSIS, the Cochrane database, Embase, Google scholar, ISI Web of Science, and Medline to identify articles, published up to April 2013, evaluating the endothelial and arterial function of migraineurs.Several lines of evidence for vascular dysfunction were reported in migraineurs. Findings regarding endothelial function are particularly controversial since studies variously indicated the presence of endothelial dysfunction in migraineurs, the absence of any difference in endothelial function between migraineurs and non-migraineurs, and even an enhanced endothelial function in migraineurs. Reports on arterial function are more consistent and suggest that functional properties of large arteries are altered in migraineurs.Peripheral vascular function, particularly arterial function, is a promising non-invasive indicator of the vascular health of subjects with migraine. However, further targeted research is needed to understand whether altered arterial function explains the increased risk of vascular disease among patients with migraine.
